As North America’s largest buyer of softwood lumber, UFP owns scale advantage in sourcing, and in serving the three largest softwood end markets – residential construction, retail building products and industrial packaging. While in its early stages, a strategic and growing focus on innovation has brought the company and its customers a steady stream of new products and services. Balanced Business Model Incentives Aligned With Shareholders Commitment To Innovation UNIQUE BUSINESS MODEL PROVIDES SUSTAINABLE COMPETITIVE ADVANTAGES This results in the company’s balanced business model, which hedges against cyclicality and customer concentration while providing advantage in procurement. The model also provides product mix diversification which mitigates against a variety of risks including lumber market volatility. This management approach encourages an entrepreneurial spirit and efficient capital allocation, resulting in high ROIC and a consistently strong balance sheet. This robust pipeline of new products, averaging 9% of sales since 2019, enables the company to win new customers and enter new markets while moving steadily up the value chain. AND DRIVES STRONG RESULTS Teamwork, accountability, devotion to the customer, and internal competition create a results-driven culture that drives personal and profession growth within the organization. This distinctive culture has delivered 67 straight years of profitability and an average tenure of 22.3 years for our 65 most senior executives. Culture Each of our 220+ operations is a profit center, managed by people who are required to own stock, and are compensated on a combination of pre-bonus operating profit and return on investment.

RETAIL Based on data such as same-store sales growth of national home improvement retailers and forecasts of home remodeling activity, we anticipate market demand to be flat to slightly down for the balance of 2023. PACKAGING Data from several metrics, including the Purchasing Managers Index (PMI), durable goods manufacturing, and U.S. real GDP, indicate that industrial production will be slightly down for the balance of 2023. CONSTRUCTION Consensus estimates of housing starts call for a 12%-15% decline in 2023. The National Association of Home Builders forecasts a 24% decrease in manufactured home shipments in 2023. MARGINS We believe our consolidated annual decremental operating margin is in a range of 10-15% of net sales. By segment we see Packaging in a range of 20-25% and Construction in a range of 14-19%. We anticipate improvement in operating profits in our Retail segment in 2023.
